android - Android 中带有对话框和 wevView 的泄漏窗口

Question

在处理来自接收 Activity 对象引用的 Java 类的多个 Web View 时，我的代码中有一个错误。

这是我的代码:

try {
            mActivity.runOnUiThread(new Runnable() {
                @SuppressLint("NewApi")
                public void run() {

                    if (webView == null)
                        return;

                    if (visibility) {
                        webView.setVisibility(View.VISIBLE);
                        webView.requestFocus();

                        if (dialog != null && !dialog.isShowing()) {
                            System.out.println("case1: " + dialog + " , activity: " + mActivity + ", mview " + webView);

                        } else {
                            dialog = WebViewUtils.showWebView(mActivity, webView);
                            System.out.println("case2 " + dialog + " , activity: " + mActivity + ", mview " + webView);
                        }
                        if (!mActivity.isFinishing()) {
                            dialog.show();
                        }
                    } else {
                        dialog.dismiss();
                        webView.setVisibility(View.GONE);
                    }
                }
            });
        } catch (Exception e) {
            System.out.println(System.out);
            Log.d(Constants.TAG, e.getMessage());
        }

这是错误堆栈:

那里声明的行在我发布的代码块中。如果我检查 Activity 是否为空或对话框是否为空，这不应该让代码不被破坏吗？我搞不清楚了。欢迎任何想法。谢谢。

只需调用 dialog.dismiss() 即可正常工作....:)
